Venting..

So I don't know if hubby and I are going to be staying together throughout this pregnancy. I'm so angry and stressed. His mother keeps saying really mean things, and when she found out we were expecting she got so angry and didn't even try to hide it. She even told that why does he always have to do everything wrong(meaning about getting me pregnant). She never liked me, but damn atleast be happy for your son! I'm so angry because she is always saying stuff like that and he never tells her anything. I don't know how much more of this I can take. I'm so tired of the entire situation with her. It's always something with her. I'm not sure I can stay with him, if he continues to let her run all over him! Any advice on what to do? BTW we got into a huge argument tonight because of her. Ugh!
